Vertical vibration isolation device
The invention discloses a vertical vibration isolation device. The vertical vibration isolation device mainly comprises an upper connecting plate, an adaptive stiffness unit, slidable oblique rectangular compression spring units and a lower connecting plate. The adaptive stiffness unit is mainly composed of a positioning loading ring, a belleville spring and a pre-compressed rectangular spring, wherein the positioning loading ring and the belleville spring work in parallel to provide vertical negative stiffness, the pre-compressed rectangular spring provides vertical positive stiffness, and the positioning loading ring, the belleville spring and the pre-compressed rectangular spring work together to generate adaptive stiffness; and the slidable oblique rectangular compression spring unitsare each composed of a directional linear guide rail, an oblique rectangular compression spring and a universal joint, vertical sliding blocks move down along the directional linear guide rails to cause axial compression deformation of the oblique rectangular springs, and energy is dissipated through the mutual conversion of elastic potential energy and kinetic energy. The adaptive stiffness unitand the slidable oblique rectangular compression spring units work in parallel, collaboratively deform and jointly achieve vertical vibration isolation. The vertical vibration isolation device can bewidely applied to buildings or large and medium-sized mechanical equipment with high requirements for vibration reduction and near rail transit.
本发明公开了一种竖向隔振装置，主要包含上连接板、自适应刚度单元、可滑动斜向矩形压缩弹簧单元、下连接板。自适应刚度单元主要由定位加载环、碟形弹簧、预压矩形弹簧组成，其中定位加载环和碟形弹簧并联工作提供竖向负刚度，预压矩形弹簧提供竖向正刚度，二者配合工作产生自适应刚度；可滑动斜向矩形压缩弹簧单元由定向线性导轨、斜向矩形压缩弹簧、万向节组成，竖向滑块沿定向线性导轨向下运动，使斜向矩形弹簧发生轴向压缩变形，通过弹性势能和动能相互转化耗散能量。自适应刚度单元与可滑动斜向矩形压缩弹簧单元并联工作，协同变形，共同实现竖向隔振。本发明可广泛应用于轨道交通附近对减振要求较高的建筑物或大中型机械设备。
